Description

Kiwi fruit yield-increasing planting method

Technical Field

The invention belongs to the field of cultivation of vegetables, flowers, rice, fruit trees, grapes, hops or sea vegetables, and particularly relates to a yield-increasing planting method for kiwi fruits.

Background

Kiwi fruit, also called exotic fruit, is an oval fruit with a greenish-brown exterior and a fluffy cuticle. The kiwi fruit is soft in texture, sour and sweet in taste, rich in organic substances such as actinidine, proteolytic enzyme, tannin pectin and saccharides, trace elements such as calcium, potassium, selenium, zinc and germanium, 17 amino acids required by human bodies, and rich in vitamin C, grape acid, fructose, citric acid, malic acid and fat, so that the kiwi fruit is called as the king of fruits. The kiwi fruits have the effects of expanding blood vessels, reducing blood pressure and blood sugar, improving immunity, treating liver diseases, dyspepsia, anemia and the like, so the kiwi fruits are widely popular among people.

Because the kiwi fruits are deeply loved by people, the kiwi fruit planting is also a preferred item for fruit growers. The kiwi fruits have the characteristic of being favored by fertilizers and burning, are not easy to survive in planting, are extremely easy to be damaged by insect pests in the growth process, and can cause low fruiting rate of the kiwi fruits. Therefore, in order to meet the market demand of the kiwi fruits, the applicant develops a kiwi fruit yield-increasing planting method.

The invention aims to provide a yield-increasing planting method for kiwi fruits, and aims to solve the problem that kiwi fruits are extremely susceptible to insect pests in the growth process and the kiwi fruit yield is low in the prior art.

In order to realize the aim, the invention provides the following technical scheme that the yield-increasing planting method of the kiwi fruits comprises the steps of land preparation, seedling culture, transplanting, topdressing and field management,

A. land preparation:

loosening the soil of the seedling raising land 30-40 days before seedling raising, removing impurities, leveling the seedling raising land according to the width of 1-1.5m, and spreading a base fertilizer to each land, wherein the base fertilizer is a mixture of plant ash, a phosphate fertilizer and a nitrogen fertilizer in a mass ratio of 1:2:1, and the amount of the spread base fertilizer is 0.8-1.2 kg/square meter; spraying 0.8-1.2% Bordeaux solution in the amount of 2-3L/square meter to the seedling growing land after applying base fertilizer for 5-10 days; sprinkling water to the seedling culture land 3-5 days before seedling culture, wherein the sprinkling water amount is 3-5L per square meter;

B. seedling culture:

soaking seeds for 24-30h by using a kiwi fruit seed soaking device, uniformly mixing the soaked seeds with wet sand with the water content of 15-20%, storing for 10-20 days, separating the seeds from the sand, scattering the seeds and the sand on the land of a carriage, wherein the scattering amount is 10-15 g/square meter, uniformly mixing the seeds with the soil of the land of the carriage, scattering the sand with the thickness of 4-8mm, and covering a film on the land of the carriage;

C. seedling management:

after 15-25 days of seed sowing, 6-7 points of the film are uncovered every day in the afternoon, and 7-8 points of the film are covered on the next morning; after 30 days of seeding, the film is taken down;

D. transplanting:

30-40 days before transplanting, spreading a mixture of a phosphate fertilizer, a nitrogen fertilizer and urea with a mass fraction ratio of 1:1:1 to a planting field, wherein the fertilizing amount is 1-1.5kg per square meter, and watering the planting field, wherein the watering amount is 2-3L per square meter; after 50-60 days of seed sowing, selecting kiwi fruit seedlings with the height of more than 30cm for transplanting; planting according to the row spacing of 5-6m and the plant spacing of 3-4m during transplanting;

And furthermore, the fertilizer applied after the planting of the step E for half a year is plant ash, phosphate fertilizer and nitrogen fertilizer with the mass portion ratio of 1:1: 1.

Has the advantages that: can provide nutrition for the growth of the branches and leaves of the kiwi fruit trees, so that the branches and leaves of the kiwi fruit trees are flourishing, and the fruiting rate of the kiwi fruit trees is improved.

Further, the fertilizer applied after planting for one year in the step E is bean cakes, organic fertilizer and plant ash with the mass part ratio of 2:2: 1.

Has the advantages that: the energy can be saved for the kiwi fruit tree, and the kiwi fruit tree is ensured to be rich in nutrition.

Further, mint is interplanted after the kiwi fruits are planted for one year.

Has the advantages that: through interplanting mint, can effectually utilize the open space between the kiwi fruit tree, the leaf of mint is great simultaneously, can play certain effect of sheltering from to planting ground, reduces earth's surface temperature, avoids the root system of kiwi fruit tree to be sunburned. And mint can give off special smell, can play the effect of expelling parasite, can less the insect pest of kiwi fruit tree, compares with using the medicine expelling parasite, can avoid the medicine to remain on the kiwi fruit tree. The mint is also a common traditional Chinese medicine and has the effects of sweating and relieving fever, and treating influenza, headache, conjunctival congestion, fever, sore throat and gum swelling, so that the mint can be used as a medicine after being planted and the income can be increased.

Further, the row spacing of the interplanted mint is 10-15 cm.

Has the advantages that: by setting the plant spacing of the mint, the utilization rate of the open space can be improved, and the growth effect of the mint is good.

Further, in the step D, before the kiwi fruit is transplanted, the kiwi fruit seedlings are soaked in the nutrient solution for 15-20min and then soaked in warm water at the temperature of 40-45 ℃ for 30-50 min.
